查看CordovaWebView的源碼，它是這樣實現的。
public CordovaWebView(Context context, AttributeSet attrs, int defStyle, boolean privateBrowsing) {
super(context, attrs, defStyle, privateBrowsing);
if (CordovaInterface.class.isInstance(context))
{
this.cordova = (CordovaInterface) context;
}
else
{
Log.d(TAG, "Your activity must implement CordovaInterface to work");
}
this.setWebChromeClient(new CordovaChromeClient(this.cordova));
this.initWebViewClient(this.cordova);
this.loadConfiguration();
this.setup();
}
所以只要讓CordovaWebView的Content是實現CordovaInterface的接口就可以了。
實現壹個類繼承接口CordovaInterface：
private ...因為CordovaWebView 默認的初始化裏判斷了Content是不是繼承CordovaInterface，如果直接使用Fragment繼承CordovaInterface，CordovaInterface有個抽象方法getActicity （）和Fragment的相沖突了，並且Fragment的這個同名方法還是final的，無法覆蓋。

實現壹個類繼承接口CordovaInterface：
private class CordovaContext extends ContextWrapper implements CordovaInterface {
Activity activity;
protected final ExecutorService threadPool = Executors.newCachedThreadPool();
public CordovaContext(Activity activity) {
super(activity.getBaseContext());
this.activity = activity;
}
public void startActivityForResult(CordovaPlugin command, Intent intent, int requestCode) {
//activity.startActivityForResult(command, intent, requestCode);
}
public void setActivityResultCallback(CordovaPlugin plugin) {
//activity.setActivityResultCallback(plugin);
}
public Activity getActivity() {
return activity;
}
public Object onMessage(String id, Object data) {
return null;
}
public ExecutorService getThreadPool() {
return threadPool;
}
}
然後在Fragment的onCreateView方法裏，更改默認的LayoutInflater inflater的content；
inflater ＝ cloneInContext(new CordovaContext(mActivity)；
這樣就可以實現Fragment裏正常使用CordovaWebView。
